DESCRIPTION OF THE PREFERRED EMBODIMENTS

The novel compounds of the present invention may be readily prepared in accordance with the following schemes. ##STR21##

The starting 9-azido-7-(substituted)-6-demethyl-6-deoxytetracycline, 1, described in formula 1 is prepared according to Scheme I. ##STR22##

In accordance with Scheme I, 9-amino-7-(substituted)-6-demethyl-6-deoxytetracycline 2, or the mineral acid or halide salt, dissolved in 0.1N methanolic hydrogen chloride, is treated for from 5 minutes to 8 hours at from -20° C. to +45° C. with an excess of n-butyl nitrite to give a 9-diazonium-7-(substituted)-6-demethyl-6-deoxytetracycline, 3, or the mineral acid or halide salt. The formed diazonium compound, 3, or the mineral acid or halide salt, dissolved in 0.1N methanolic hydrogen chloride, is treated for 5 minutes to 8 hours at from -5° C. to +50° C. with one equivalent of sodium azide to give the corresponding 9-azido-7-(substituted)-6-demethyl-6-deoxytetracycline, 1, or the mineral acid or halide salt. ##STR23##

In accordance with Scheme II, a 9-azido-7-(substituted)-6-demethyl-6-deoxytetracycline, 1, or the mineral acid or halide salt, is treated for from 5 minutes to 12 hours at from -5° C. to 40° C. with a strong acid, such as sulfuric acid, hydrochloric acid, methanesulfonic acid, trifluoromethanesulfonic acid, hydrobromic, hydroiodic, or hydrogen fluoride to produce a 9-amino-7-(substituted)-8-(substituted)-6-demethyl-6-deoxytetracycline, 4, or the mineral acid or halide salt.

The 9-amino-7-(substituted)-8-(substituted)-6-demethyl-6-deoxytetracycline, 4, or the mineral acid or halide salt, can be further converted as described in Scheme III. ##STR24##

In accordance with Scheme III, a 9-amino-7-(substituted-8-(substituted)-6-demethyl-6-deoxytetracycline, 4, or the mineral acid or halide salt, is treated at room temperature for from 0.5-2 hours with an acid chloride of the formula: ##STR25## wherein R³, R⁴, W and X are defined hereinabove; in the presence of a suitable acid scavenger, in a suitable solvent, to form the corresponding 9-[(substituted glycyl)amido]-7-(substituted)-8-(substituted)-6-demethyl-6-deoxytetracycline, 5, or the mineral acid or halide salt.

The acid scavenger is selected from sodium bicarbonate, sodium acetate, pyridine, triethylamine, N,O-bis(trimethylsilyl)acetamide, N,O-bis(trimethylsilyl)trifluoroacetamide, potassium carbonate, a basic ion exchange resin or equivalent thereof.

The solvents are selected from water, tetrahydrofuran, N-methylpyrrolidone, 1,3-dimethyl-2-imidazolidinone, hexamethylphosphoramide, 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)pyrimidinone, 1,2-dimethoxyethane or equivalent thereof.

Alternatively, in accordance with Scheme III, 9-amino-7-(substituted)-8-(substituted)-6-demethyl-6-deoxytetracycline, 4, or the mineral acid or halide salt, is treated with a straight or branched chain α-haloacyl halide of the formula: ##STR26## wherein R³, R⁴ and Y are defined hereinabove and Q is halogen selected from bromine, chlorine, fluorine and iodine, such as bromacetyl bromide, chloroacetyl chloride, 2-bromopropionyl bromide or equivalent thereof; in the presence of a suitable acid scavenger, in a suitable of solvent, to form the corresponding 9-[(haloacyl)amido]-7-(substituted)-8-(substituted)-6-demethyl-6-deoxytetracycline, 6, or the mineral acid or halide salt.

The halogen, Y, and halide, Q, in the haloacyl halide can be the same or different halogen and are selected from bromine, chlorine, iodine and fluorine; Y is (CH₂)_(n) X', n=0-5 and X' is a halogen.

The acid scavenger and suitable solvent are as defined hereinabove.

The 9-[(haloacyl)amido]-7-(substituted)-8-(substituted)-6-demethyl-6-deoxytetracycline, 6, or mineral acid or halide salt, is treated, under an inert atmosphere of nitrogen, argon or helium, with nucleophiles of the formula, WH, where W is defined hereinabove, such as amines or substituted amines or equivalents thereof, in a suitable solvent to form the corresponding 9-[(substituted glycyl)amido]-7-(substituted)-8-(substituted)-6-demethyl -6-deoxytetracycline, 5, or mineral acid or halide salt. ##STR27##

In accordance with Scheme IV, compound 5 is selectively N-alkylated in the presence of formaldehyde and either a primary amine of the formula R⁵ NH₂ such as methylamine, ethylamine, benzylamine, methyl glycinate, (L or D)lysine, (L or D)alanine or their substituted congeners; or a secondary amine of the formula R⁵ R⁶ NH such as morpholine, pyrrolidine, piperidine or their substituted congeners to give the corresponding Mannich base adduct, 7.

The 9-[(substituted glycyl)amido]-7-(substituted)-8-(substituted)-6-demethyl-6-deoxytetracyclines may be obtained as metal complexes such as aluminum, calcium, iron, magnesium, manganese and complex salts; inorganic and organic salts and corresponding Mannich base adducts using methods known to those skilled in the art (Richard C. Larock, Comprehensive Organic transformations, VCH Publishers, 411-415, 1989). Preferably, the 7-(substituted)-8-(substituted)-9-(substituted)-6-demethyl-6-deoxytetracyclines are obtained as inorganic salts such as hydrochloric, hydrobromic, hydroiodic, phosphoric, nitric or sulfate; or organic salts such as acetate, benzoate, citrate, cysteine or other amino acids, fumarate, glycolate, maleate, succinate, tartrate, alkylsulfonate or arylsulfonate. Depending on the stoichiometry of the acids used, the salt formation occurs with the C(4)-dimethylamino group (1 equivalent of acid) or with both the C(4)-dimethylamino or the W group (2 equivalents of acid). The salts are preferred for oral and parenteral administration.

Some of the compounds of the hereinbefore described Schemes have centers of asymmetry at the carbon bearing the W substituent. The compounds may, therefore, exist in at least two (2) stereoisomeric forms. The present invention encompasses all stereoisomers of the compounds whether free from other stereoisomers or admixed with stereoisomers in any proportion of enantiomers. The absolute configuration of any compound may be determined by conventional X-ray crystallography.

The stereochemistry centers on the tetracycline unit (i.e., C-4, C-4a, C-5a and C-12a) remain intact throughout the reaction sequences.

BIOLOGICAL ACTIVITY

Methods for in Vitro antibacterial evaluation

(Table I)

The minimum inhibitory concentration (MIC), the lowest concentration of the antibiotic which inhibits growth of the test organism, is determined by the agar dilution method using 0.1 ml Muller-Hinton II agar (Baltimore Biological Laboratories) per well. An inoculum level of 1-5×10⁵ CFU/ml, and a range of antibiotic concentrations (32--0.004 microgram/ml) is used. MIC is determined after the plates are incubated for 18 hours at 35° C. in a forced air incubator. The test organisms comprise genetically defined strains that are sensitive to tetracycline and resistant strains that are insensitive to tetracycline, either by preventing the antibiotic from interacting with bacterial ribosomes (tetM) or by a tetK encoded membrane protein which confers tetracycline resistance by energy-dependent efflux of the antibiotic from the cell.

Testing Results

The claimed compounds exhibit antibacterial activity against a spectrum of tetracycline sensitive and resistant Gram-positive and Gram-negative bacteria, especially, strains of E. coli, S. aureus and E. faecalis, containing the tetM resistance determinants (Table I). Notable is 8-chloro-9-(N,N-dimethylglycylamido)-6-demethyl-6-deoxytetracycline, as shown in Table I, which has good in vitro activity against tetracycline resistant strains containing the tetM resistance determinant (such as S. aureus UBMS 88-5, S. aureus UBMS 90-1 and 90-2, E. coli UBMS 89-1 and 90-4) and is equally as effective as minocycline against susceptible strains.

Most importantly, these compounds also exhibit antibacterial activity against bacteria that contain an active efflux resistant mechanism as in tetA, tetB, or tetK (i.e., E. coli UBMS 88-1, E. coli PRPI tetA, E. coli Me4100 TN10-tetB, and S. aureua UBMS 88-7 tetK).

As can be seen from Table I, compounds of the invention may be used to prevent or control important mammalian and veterinary disease such as diarrhea, urinary tract infections, infections of skin and skin structure, ear, nose and throat infections, wound infections, mastitis and the like.

When the compounds are employed as antibacterials, they can be combined with one or more pharmaceutically acceptable carriers, for example, solvents, diluents and the like, and may be administered orally in such forms as tablets, capsules, dispersible powders, granules, or suspensions containing, for example, from about 0.05 to 5% of suspending agent, syrups containing, for example, from about 10 to 50% of sugar, and elixirs containing for example, from about 20 to 50% ethanol and the like, or parenterally in the form of sterile injectable solutions or suspensions containing from about 0.05 to 5% suspending agent in an isotonic medium. Such pharmaceutical preparations may contain, for example, from about 25 to about 90% of the active ingredient in combination with the carrier, more usually between about 5% and 60% by weight.

An effective amount of compound from 2.0 mg/kg of body weight to 100.0 mg/kg of body weight should be administered one to five times per day via any typical route of administration including but not limited to oral, parenteral (including subcutaneous, intraveneous, intramuscular, intrasternal injection or infusion techniques), topical or rectal, in dosage unit formulations containing conventional non-toxic pharmaceutically acceptable carriers, adjuvants and vehicles. It will be understood, however, that the specific dose level and frequency of dosage for any particular patient may be varied and will depend upon a variety of factors including the activity of the specific compound employed, the metabolic stability and length of action of that compound, the age, body weight, general health, sex, diet, mode and time of administration, rate of excretion, drug combination, the severity of the particular condition, and the host undergoing therapy.

These active compounds may be administered orally as well as by intravenous, intramuscular, or subcutaneous routes. Solid carriers include starch, lactose, dicalcium phosphate, microcrystalline cellulose, sucrose and kaolin, while liquid carriers include sterile water, polyethylene glycols, non-ionic surfactants and edible oils such as corn, peanut and sesame oils, as are appropriate to the nature of the active ingredient and the particular form of administration desired. Adjuvants customarily employed in the preparation of pharmaceutical compositions may be advantageously included, such as flavoring agents, coloring agents, preserving agents, and antioxidants, for example, vitamin E, ascorbic acid, BHT and BHA.

The preferred pharmaceutical compositions from the standpoint of ease of preparation and administration are solid compositions, particularly tablets and hard-filled or liquid-filled capsules. Oral administration of the compounds is preferred.

These active compounds may also be administered parenterally or intraperitoneally. Solutions or suspensions of these active compounds as a free base or pharmacologically acceptable salt can be prepared in glycerol, liquid, polyethylene glycols and mixtures thereof in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms.

The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases, the form must be sterile and must be fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and must be preserve against the contaminating action of microorganisms such as bacterial and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol and liquid polyethylene glycol), suitable mixtures thereof, and vegetable oil.
